The purpose was to develop and evaluate a novel approach to MR phase imaging of blood flow and CSF flow by combining cine phase contrast (cine-PC) with simultaneous multi-slice (SMS) technique to measure velocity in several slice planes simultaneously. Comparisons were made between SMS 2-4 and conventional single-slice 2D cine-PC GE imaging. The velocity curves measured in internal carotid (ICA) and vertebral arteries and jugular veins and aqueductal CSF were similar between SMS and conventional single-slice cine-PC. In ICA correlations (R=0.92-0.98) in 6 subjects. This new ability for simultaneous cross-sectional hemodynamic quantification may be useful for medical diagnoses.
